Stereo & Electronics - Bulb issue with HID headlights

alright, so i bought an hid headlight kit off of ledgauges.com, installed, and all was right with the world, then about a week later one of the little bastards burned out...i figure the installer touched the damn thing with his bare hand, but thats beside the point.
All of a sudden i realized, i dont know what size bulb these things are to replace.
anyone else buy the hid lowbeam kit from them, for a 98-02 ta, and know what size bulb i need?

nevermind.
The guy over there followed up, and when i told him about the issue he told me not to buy anything. Ship him the bulb, and he'll send one no questions asked. If the ballast is the problem, hell replace that too.
Gotta love standup people.
